Answer:
340.9°k ~ 67.8°C
Explanation:
This is an example of Gay-Lussac's law, which states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. This means that if the volume increases, so does the temperature, and vice versa.
The equation for this gas law is:
P1/T1 = P2/T2
Known
P1 = 198 kPa
T1 = 27°C + 273.15 = 300°K ← Temp. must be in Kelvins
P2 = 225 kPa
T2 = ?
Solution
Rearrange the equation to isolate T2
Input the known values and solve.
T2 = T1P2/P1
Where:
T2 = 300°K × 225kPa/198kPa = 340.91°K
T2 in °C = 340.91°K − 273.15 = 67.8°C
note: answers were rounded off to one decimal point.
It is so because warm air is lighter than cold air. Cold air means the molecules are not moving as much, so they will feel like sticking together and will not jump around as molecules in warm air will(higher temp. means higher KE). Think of a solid, colder solids are much heavier than warmer ones(think of ice-starts melting).
Answer : Option B) Energy from the environment fuels production.
Explanation : Environmental fuels can be produced from lands and contribute towards production. The land can contribute for the production of a Biogas plant and help in generating energy from the plant. It uses mainly decaying matter and household wastes which are decomposed and then produce methane gas is then connected to the household kitchens.
Answer:
Balancing Strategies: To balance this reaction it is best to get the Oxygen atoms on the reactant side of the equation to an even number. Once this is done everything else falls into place. Put a "2" in front of the NaClO3. Change the coefficient in front of the O2.
